I exported a .sif file from Inkscape (version 0.48+devel+12966) (attached). Synfig (0.65.0-20140120) can open this file but none of the objects can be animated. In fact, the time track doesn’t appear at all and the + sign for adding keyframes is greyed out.
Additionally, when I try to move or manipulate a group of objects I get this error:
Is this a bug in the .sif exporter in Inkscape, Synfig, or just an option that needs changing? drawing.sif (13.2 KB)
Files exported from Inkscape doesn’t seem to have a duration. You need to manually change the duration from 1 frame to the value you want. Go to Menu->Edit->Properties and modify the start and end times in the Time tab.
You’re using a development version so that’s the reason it can’t be modified. Use a later development version or an earlier stable version to be able to animate it properly.
